ABDOMINAL CAVITY 



The lower and posterior surfaces are both divided into 

 segments by a right and a left pair of fossae which run 

 parallel with the sagittal plane. The left pair of sagittal fossae, 

 which separate the lower and the posterior surfaces into right 

 and left lobes, are the fossa for the umbilical vein on the 

 inferior surface, and the fossa for the ductus venosus on the 

 posterior surface. The right pair of sagittal fossae, which 

 segment the lower and posterior surfaces of the right lobe, 

 are the fossa for the gall-bladder on the lower surface and the 

 fossa for the inferior vena cava on the posterior surface.

 FIG. 200. Posterior Surface of the Liver. 



The Lower Surface of the Liver looks downwards and 

 backwards and rests either upon viscera situated at a lower 

 level in the abdomen or upon the front of the lesser omentum. 

 It is separated into a smaller right and a larger left segment 

 or lobe by the fossa for the umbilical vein. On the lower 

 surface of the right lobe, close to its posterior border and at 

 its left extremity, is the porta hepatis or hilus of the liver, 

 through which the hepatic artery and the portal vein pass 

 into the liver and the bile-ducts and the lymph vessels pass 

 out. It connects the posterior part of the fossa for the umbilical 

 vein with the posterior part of the fossa for the gall-bladder.
